The average slimes dam compacts at 0,625 m3 per tonne and contains 10 per cent moisture. At 0,625 m3 per tonne, the slime would become saturated at 20 per cent moisture. For example, a slimes dam 15 m high constructed on 85 ha of ground would contain nearly 18 million tonne of solids at 10 per cent moisture, and a slimes dam 35 m …

Retreatment of Gold Residues

 — Gold-mining residues typically fall into one of three categories: slime (particle size of about 75% passing 74 μm), sand (about 10–20% passing 74 μm), and waste rock. Since the slime and sand have been previously processed, it typically has a low gold grade (<1.0 g/t) and will provide relatively low recovery efficiencies, in the order of 50%.
